Back when rugby socks were made of stretchy cotton or wool, players improvised strings
to help tie them up. The tie restricts blood, comes untied, and doesn't work. You need support, not a tourniquet!
This is why you will not see International, Provincial or Select players wearing tie socks. Ruggers socks have built-in elastic at the cuff, ankle and arch. They stay up and perform and are an outstanding value.
